As in water face answereth to face, {h} so the heart of man to man.

(h) There is no difference between men by nature, only the grace of God makes the difference.

Wesley's Notes

27:19 So - So one man resembles another in the corruption of his nature.

Jamieson-Fausset-Brown Bible Commentary

19. We may see our characters in the developed tempers of others.

Matthew Henry's Concise Commentary

27:15,16. The contentions of a neighbour may be like a sharp shower, troublesome for a time; the contentions of a wife are like constant rain. 17. We are cautioned to take heed whom we converse with. And directed to have in view, in conversation, to make one another wiser and better. 18. Though a calling be laborious and despised, yet those who keep to it, will find there is something to be got by it. God is a Master who has engaged to honour those who serve him faithfully. 19. One corrupt heart is like another; so are sanctified hearts: the former bear the same image of the earthly, the latter the same image of the heavenly. Let us carefully watch our own hearts, comparing them with the word of God. 20. Two things are here said to be never satisfied, death and sin. The appetites of the carnal mind for profit or pleasure are always desiring more. Those whose eyes are ever toward the Lord, are satisfied in him, and shall for ever be so. 21. Silver and gold are tried by putting them into the furnace and fining-pot; so is a man tried by praising him. 22. Some are so bad, that even severe methods do not answer the end; what remains but that they should be rejected? The new-creating power of God's grace alone is able to make a change. 23-27. We ought to have some business to do in this world, and not to live in idleness, and not to meddle with what we do not understand. We must be diligent and take pains. Let us do what we can, still the world cannot be secured to us, therefore we must choose a more lasting portion; but by the blessing of God upon our honest labours, we may expect to enjoy as much of earthly blessings as is good for us.

Matthew Henry's Whole Bible Commentary

Verse 19

This shows us that there is a way, 1. Of knowing ourselves. As the water is a looking-glass in which we may see our faces by reflection, so there are mirrors by which the heart of a man is discovered to a man, that is, to himself. Let a man examine his own conscience, his thoughts, affections, and intentions. Let him behold his natural face in the glass of the divine law (Jam. 1:23), and he may discern what kind of man he is and what is his true character, which it will be of great use to every man rightly to know. 2. Of knowing one another by ourselves; for, as there is a similitude between the face of a man and the reflection of it in the water, so there is between one man's heart and another's for God has fashioned men's hearts alike; and in many cases we may judge of others by ourselves, which is one of the foundations on which that rule is built of doing to others as we would be done by, Ex. 23:9 Nihil est unum uni tam simile, tam par, quam omnes inter nosmet ipsos sumus. Sui nemo ipse tam similis quam omnes sunt omnium-No one thing is so like another as man is to man. No person is so like himself as each person is to all besides. Cic. de Legib. lib. 1. One corrupt heart is like another, and so is one sanctified heart, for the former bears the same image of the earthy, the latter the same image of the heavenly.
